Von Duprin 99EO-F 3 US26D – Frequently Asked Questions

1) Will the Von Duprin 99F-3FT fit a 1-3/4 inch metal door?
Yes. The 99F-3FT is built for 1-3/4 inch doors, and the fastener pack covers wood or metal doors at 1-3/4 inch and 2-1/4 inch thick. It's sized for a 36 inch door leaf with a wide stile push pad. Note the catalog record marks it as not wood door compatible, so plan it on a hollow metal or metal-faced opening.
2) Is the Von Duprin 99F-3FT fire rated for a labeled door opening?
It is. The 99F carries a fire rating and is certified to ANSI/BHMA A156.3 2014 Grade 1, with UL listings including ANSI/UL 10C and CAN/ULC-S104 for fire door assemblies, plus ANSI/UL 305 and CAN/ULC-S132 for panic hardware. The practical consequence of the fire listing: this device is furnished less dogging, because a fire exit device must latch every time the door closes. If you need hold-open dogging for daytime traffic, you need a non-fire device instead.
3) Does the 99F rim exit device need to be ordered handed?
The device itself is non-handed, so the same 99F chassis works on a right or left hand reverse opening. Two exceptions: handing does become a factor when SD, -2, or SS options are specified, and handing is a required selection when you configure it (RHR or LHR) because the trim and switch options follow the door swing.
4) Will the 99F latch into my existing rim strike?
The 99F throws a 3/4 inch latchbolt into a surface-applied rim strike on the frame stop, and the device projects 3-13/16 inch off the door face. Rim devices latch into a strike on the frame, not into the floor or head, so a single door or a pair with a center mullion is the application. On a pair with no mullion, a rim device has nothing to latch into, and you want a vertical rod configuration instead.
5) I have a pair of doors with no mullion. Can I still use the Von Duprin 98/99 platform?
Not with the rim 99F, which latches into a frame strike. The 98/99 platform covers the other device types you'd need on that opening: surface vertical rod (27), concealed vertical rod with a 5/8 inch bottom bolt (47), concealed vertical rod with a 1-1/2 inch bottom bolt (48), concealed vertical cable (49), 1-point concealed cable (52), 3-point latching (57), and mortise (75). For a pair without a mullion, a vertical rod or cable device latches at head and sill instead.
6) What outside trim can I get with the Von Duprin 99F, and what do I have to specify?
Thirteen trim functions are offered: exit only, night latch, night latch with optional pull, knob, knob with blank escutcheon, knob night latch, lever, lever with blank escutcheon, lever key capture, lever night latch, thumbpiece, thumbpiece with blank escutcheon, and dummy trim. If you pick an L lever function you also choose the lever design, 01, 02, 03, 05, 06, 07, 17, or 18, with 06 as the default. Handing (RHR or LHR) is a required pick, and so are the AX accessible option, QM quiet mechanical, bar style, and whether you want CXA delayed egress.
7) Can I get the 99F with electric latch retraction and a request-to-exit switch for access control?
Yes, and both are ordering options on the device rather than field add-ons. Latch retraction comes as EL electric, QEL quiet electric, or PN pneumatic. Switch choices run RX request to exit, LX latchbolt monitor, LX-RX combination, WP-RX waterproof RX, RX-LC low current, RX-2 double RX, SS signal switch, and the ALK alarm exit kit in less-switch, RX, and LX/RX versions. Specify the switch and the retraction option at order time so the device ships prepped.
8) What else could I buy instead of the Von Duprin 99F for a fire rated 36 inch door?
Three direct alternatives on a labeled 36 inch opening: the Marks USA M9900F 36 inch fire rated rim device, exit only with a panic protector end cap; the Orca Hardware OED85 Series 36 inch fire rated rim device, exit only; and the Dexter ED1000 Series fire rated rim device, Grade 1. The Sargent 12-8810-LTRIM is a fire rated Grade 1 wide stile rim device that comes with RX and motorized electric latch retraction already built in, which is the closer match if you were going to specify the 99F with QEL and RX anyway. Note the Marks, Orca, and Dexter options listed here are exit only, so they take no outside trim.
9) Can I use a non-fire-rated rim exit device on a fire door if the rest of the specs match?
No, and it's the most common substitution mistake on this kind of part. The 99F is fire rated; the wide stile devices that look nearly identical are not. The BEST Precision 2101 36 inch wide stile, Corbin Russwin ED5200 36 inch wide stile, TownSteel ED1100 36 inch Grade 1 wide stile, DORMA 8300 wide stile, and Detex 10 Advantex 36 inch wide stile are all wide stile rim devices with no fire rating. Those are fine on a non-labeled egress door and wrong on a labeled one.
10) The door is an aluminum storefront with a narrow stile. Will a 99F-3FT fit, and what should I use instead?
The 99F-3FT is a wide stile device with a center case measuring 8 inches by 2-3/4 inches by 2-3/8 inches, which needs more stile face than an aluminum storefront door gives you. For a narrow stile opening that still has to be fire rated, the Adams Rite 3700 Series is a 30 inch fire rated Grade 1 narrow stile rim exit device with starwheel interlocking. If the storefront opening is not fire rated, narrow stile Grade 1 options include the Corbin Russwin ED4200 at 36 inches, the Falcon 19-R at 36 inches in exit only, and the Adams Rite 8800 Series at 30 inches. Match the stile type to the door before matching anything else - a wide stile case will not land on a narrow stile.
11) The opening is a 48 inch door, not 36 inch. What replaces the 99F-3FT there?
The 99F-3FT is sized for a 36 inch door, so a 48 inch leaf needs a longer device. Fire rated at 48 inches, the Marks USA M9900F-48 is a 48 inch fire rated rim panic exit device in exit only with a panic protector end cap. If the 48 inch opening is not fire rated, the Corbin Russwin ED3200 is a Grade 1 48 inch crossbar rim device, the DORMA 9300A is a 48 inch wide stile Grade 1 rim device in exit only, and the Sargent 3828 is a Grade 1 reversible push bar rim device for 48 inch doors. The Von Duprin 98/99 platform also runs longer than 3 feet, so staying in series is possible if you want the same case and trim across a facility.
12) What is the closest fire rated wide stile rim exit device to the Von Duprin 99F-3FT if the 99 Series is not an option?
The Sargent 8800 Series 12-8810-LTRIM is the nearest match on the core attributes that matter for a fire door: it is a fire rated, Grade 1, wide stile rim exit device, the same combination the 99F-3FT carries at ANSI/BHMA Grade 1 with a wide stile push pad case. The 99F-3FT is sized for a 36 inch door with a 3/4 inch latch throw. The Sargent unit ships as a dummy function device with L trim, so confirm the function you need on the opening before treating it as a drop-in for a latching 99F. For a fire rated wide stile device in a straightforward exit only function, the Marks USA M9900F-36 is a 36 inch fire rated rim device in exit only.
13) Can I use a Von Duprin 99-3FT non fire rated device where a 99F-3FT is specified?
No. The F in 99F is the fire rated designation, and the 99F-3FT is listed to ANSI/UL 10C and CAN/ULC-S104 for fire rated openings, which is why it is supplied less dogging - a fire door cannot have its latch held retracted. Devices without a fire rating cannot go on a fire rated opening no matter how closely they match on grade or stile. That rules out a long list of otherwise similar wide stile Grade 1 rim devices for this application: the Corbin Russwin ED5200, the DORMA 8300 Series, the TownSteel ED1100, and the BEST Precision 2101 are all wide stile rim devices with no fire rating. If the opening is fire rated, the substitute has to carry the rating itself.
14) What looks like a substitute for a 99F-3FT rim device but actually is not?
Three categories catch people out. First, exit bars that are not latching panic hardware: the SDC MSB550 Series 36 inch mechanical switch bar releases an electromagnetic lock and the SDC SureExit PSB560 Series 36 inch pressure sense bar works the same way - they signal, they do not throw a 3/4 inch latch into a strike the way the 99F-3FT does, and neither is fire rated. Second, dummy devices: the Detex Advantex 00 Series is a wide stile Grade 1 dummy exit device with no working latch, meant to match appearance on an inactive leaf. Third, a different device type behind a similar looking push pad: the Hager 4501 Series 36 inch wide stile pushpad device is concealed vertical rod, not rim, so it latches top and bottom into the frame and sill and needs entirely different door prep.
15) What should I use if the opening needs hex key dogging rather than a less dogging device?
The 99F-3FT is supplied less dogging, which is correct for a fire rated opening - a fire door cannot have its latch held retracted. If the door is not fire rated and you want the latch dogged open during business hours, the Design Hardware 1000R is a 33 inch heavy duty rim device with hex key dogging, the Design Hardware 2000R is a 33 inch standard duty wide stile rim device with hex key dogging, and the Stanley Security QED200 Series is a Grade 1 heavy duty narrow stile rim device with hex key dogging. None of those three carry a fire rating in the way the 99F does, which is exactly why dogging is available on them.
16) What is the difference between the Von Duprin 98 and 99 Series?
Mechanism case appearance. The 99 Series has a grooved mechanism case; the 98 is the smooth-case version of the same platform. The 99F-3FT carries a center case measuring 8 x 2-3/4 x 2-3/8 inches. Function, grade, and mounting are the same family, so pick on the look you're matching in the building.
17) Does the Von Duprin 99F meet the 5 lb operating force requirement for accessible openings?
With the AX accessible device option, yes. AX is the accessible upgrade rated at 5 lb. operating force, and it's a yes/no selection you make when configuring the device. Without AX you get the standard push pad force.
18) I need a 15 second delayed egress exit device for a memory care or retail door. Does the 99F do that?
It does, with the CX CHEXIT option, offered as CXA 15 second delay when you configure the device. A standard device holds the door secure for 15 seconds after a request to exit while a nuisance alarm sounds, which is the delay period NFPA and IBC recognize. Because the 99F is fire rated, this is a route to delayed egress on a labeled opening rather than adding a separate mag-lock and sensor package.
19) Can I upgrade a Von Duprin 99F later without replacing the whole device?
The 98/99 platform takes a range of field retrofit kits: CDSI and HDSI security dogging indicators, QEL quiet electric latch retraction, RX request-to-exit switches, LX latchbolt monitoring, the AX accessible upgrade, CX CHEXIT delayed egress, and the XP patented 2-piece latchbolt. That matters on a fleet of institutional openings, where the access control scope tends to arrive a year after the doors do.
20) The opening is a 36 inch fire rated door but the device does not need trim or electrification. What is a simpler alternative to the 99F-3FT?
For a fire rated 36 inch opening where the door only needs to swing out and nothing operates it from the corridor side, an exit only device removes the trim and cylinder side of the specification entirely. The Orca Hardware OED85 Series is a 36 inch fire rated rim exit device in exit only function, and the Marks USA M9900F-36 is a 36 inch fire rated rim device in exit only with a panic protector end cap. The Dexter ED1000 Series fire rated rim device is Grade 1 and fire rated as well. The 99F-3FT covers exit only too, but its value is the field configurable platform behind it - trim functions from dummy through night latch and lever key capture, plus switch and latch retraction options - so if none of that is on the drawing, a fixed exit only device answers the same opening with far less to specify.
21) Is the 99F-3FT the right choice for a wood door, and what fits a wood door instead?
The 99F-3FT is not wood door compatible as a rim device, even though its fasteners are supplied for wood or metal doors at 1-3/4 inch and 2-1/4 inch thickness. Among the comparable rim devices, the Adams Rite 3700 Series is fire rated, Grade 1, narrow stile and wood door compatible, and the non fire rated Adams Rite 8700 Series is wood door compatible as well. Within the Von Duprin 98/99 platform itself, wood door openings are addressed by the 47WDC wood door concealed vertical rod and 50WDC wood door concealed vertical cable device types rather than by the rim configuration.
22) How does a Grade 2 rim exit device compare to the 99F-3FT for a school or hospital corridor?
The 99F-3FT is certified to ANSI/BHMA A156.3 2014 Grade 1, the highest exit device grade, and is built for high use and high abuse institutional environments. The Cal-Royal 5000 is a 36 inch wide rim exit device with a touch bar on a Grade 2 chassis, and the Cal-Royal 5500 is a 48 inch push bar device at Grade 2 - both are heavy duty but sit at a different certification level, and neither is fire rated. If the specification on the drawing calls out Grade 1 or the opening is fire rated, a Grade 2 device does not satisfy it. Grade 1 wide stile alternatives that hold the certification include the Detex 10 Advantex Series at 36 inches, rated extra heavy duty, and the TownSteel ED1100 at 36 inches, though those are not fire rated.
23) I need electric latch retraction on a rim exit device. How does the 99F-3FT compare to buying an electrified device outright?
The 99F-3FT is ordered with electric latch retraction built into the configuration - EL, QEL quiet electric latch retraction, or PN pneumatic - alongside switch options including RX request to exit, LX latch bolt monitor, and the LX-RX combination, so one part number covers the mechanical device and the electrification on a fire rated opening. Among the comparables, the SDC S6136 Spectra S6000 Series is a 36 inch electrified architectural rim exit device with a 4 inch wide stile and a 1-3/4 inch to 2 inch door thickness range, and the Dormakaba E2103-4908A-36 is an electrified 36 inch rim device with 4908A trim in an 08 classroom function. Neither of those SDC or Dormakaba units carries a fire rating in the same way the 99F does, so on a fire door the electrified 99F configuration is the one that keeps the listing intact.
24) The door is 2-1/4 inches thick. Does the 99F-3FT suit it, and what else handles that thickness?
The 99F-3FT is specified for a 1-3/4 inch door thickness, and its fasteners are supplied for wood or metal doors 1-3/4 inch and 2-1/4 inch thick, so confirm the thickness against the device before ordering for a thick leaf. Comparable rim devices that publish a range reaching 2-1/4 inches include the Adams Rite 8800 Series at 1-3/4 inch to 2-1/4 inch and the DORMA 9300A at 1-3/4 inch to 2-1/4 inch, though neither is fire rated. The Securitron EMB electromechanical exit bar is listed at 2-1/4 inch. Most of the comparable rim set - the Corbin Russwin ED5200, the Falcon 19-R, the Arrow ED910 - sits at 1-3/4 inch only.
25) I need a night latch function rim device. Can I get that on the 99F-3FT or should I look elsewhere?
Night latch is available directly on the 99F-3FT through its trim functions, which include NL night latch, NL-OP night latch with optional pull, K-NL knob night latch, and L-NL lever night latch, all on a fire rated Grade 1 device. If the opening does not need a fire rating and a narrow stile suits the door, the Sargent 8504 is a Grade 1 narrow stile rim device in night latch function. The Detex V4003A/03AN is a Grade 1 wide stile rim device offered with night latch trim. The advantage of staying with the 99F for a fire door is that the night latch function comes without giving up the UL 10C listing.
26) What finishes does the Von Duprin 99F rim exit device come in?
Twelve: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome, 626 satin chrome, 628 aluminum, 630 satin stainless steel, 643E aged bronze, 710 dark bronze anodized, and 711 flat black. For matching existing openings in a building, 626 and 630 are the two that turn up most on institutional work.
27) Can I add a braille or glow-in-the-dark push bar to the Von Duprin 99F?
Yes. Bar style is a required pick at order time, with five choices: standard bar, BR braille push bar, KN knurled bar, RSS emergency exit push bar, and SG safety glow push bar. Knurled bars are the usual call where code or facility policy wants a tactile warning on a door that isn't a normal egress route.
28) Can I quiet down a Von Duprin exit device on a hospital or school corridor?
Two options address noise on the 99F. QM quiet mechanical is a yes/no selection on the device itself, and if you're electrifying the latch, QEL quiet electric latch retraction is the low-noise version of EL. Both are ordering choices, so specify them up front rather than planning to change the device later.
29) Is a crossbar rim device an equivalent to the 99F-3FT?
Not on operation or appearance. The 99F-3FT is a push pad device with a grooved mechanism case, the styling that separates the 99 Series from the smooth case 98 Series. Crossbar devices operate on a horizontal bar spanning the door instead: the Corbin Russwin ED3200 is a Grade 1 48 inch crossbar rim device supplied as panic device only, and the CRL Jackson 1095 Series is a 48 inch crossbar rim panic device in exit only, wide stile, not fire rated. If a building has been standardized on push pads, a crossbar reads as a different device on the wall and the trim and prep do not carry across. Push pad wide stile peers include the CRL Jackson 1295 Series non handed push pad device and the Arrow 3880 Series 30 inch wide stile pushpad in exit only.
30) Does a non handed rim device from another brand save the same specification work as the 99F-3FT?
The 99F-3FT rim device is non handed, which removes handing from the ordering decision for the device body itself, with exceptions when SD, -2, or SS options are applied. Other non handed rim devices in the comparable set include the BEST Precision 5101 Series, described as a non handed universal design, the BEST 2401 Series narrow stile exit only device, and the CRL Jackson 1295 Series non handed push pad rim panic device. The Sargent 2828 and 3828 achieve the same flexibility as reversible devices for 48 inch minimum door width. Where the 99F still asks for handing is the trim: lever and knob trim functions are ordered RHR or LHR.
